我有这段代码
function calculateTotal() {
var total = 0;
$(".quantity").each(function()
{
if (!isNaN(this.value) && this.value.length != 0)
{
total += parseFloat(this.value);
}
});
$("#total_quantity").val(total);
}
<input onchange="calculateTotal();" name="sol1" type="text" class="result_form_textbox_small quantity" id="sol1" />
<input name="total_quantity" type="text" class="result_form_textbox_small" id="total_quantity" />
此代码在IE中工作非常好,但它在FF中不起作用。
什么是问题?
提前致谢。

使用
$(this).val()
而不是
this.value
答案 1 :(得分:2)
问题是,对于包含您的功能的脚本,您有type="text/jscript"
而不是type="text/javascript"
。
答案 2 :(得分:1)
试试这个:
<强> HTML 强>
<input name="sol1" type="text" class="result_form_textbox_small quantity" id="sol1" />
<input name="total_quantity" type="text" class="result_form_textbox_small" id="total_quantity" />
<强> JS 强>
function calculateSum() {
var sum = 0;
//iterate through each textboxes and add the values
$(".quantity").each(function() {
//add only if the value is number
if(!isNaN(this.value) && this.value.length!=0) {
sum += parseFloat(this.value);
}
});
//.toFixed() method will roundoff the final sum to 2 decimal places
$("#total_quantity").val(sum.toFixed(2));
}
$(document).ready(function() {
$('.quantity').keyup(function() {
calculateSum();
});
});

您还可以使用以下内容:
$(this).attr("value","");
